NewCVE-2025-9232 (opens in a new tab)How to fix?
Upgrade openssl to version 3.0.18, 3.2.0-alpha1, 3.2.6, 3.3.5, 3.4.3, 3.5.4 or higher.
Overview
Affected versions of this package are vulnerable to Out-of-bounds Read due to a missing NULL byte termination after strncpy() call. An attacker can cause a crash and disrupt application availability by triggering an out-of-bounds read if API functions of OpenSSL HTTP client are used while the no_proxy environment variable is set and the host portion of the authority component of the HTTP URL is an IPv6 address.
Note:
The FIPS modules in 3.5, 3.4, 3.3, 3.2, 3.1 and 3.0 are not affected by this issue, as the HTTP client implementation is outside the OpenSSL FIPS module boundary.
